Abstract: When an injection stretch blow molding machine in which the molding cycle is tried to be shortened manufactures hollow molded bodies, blow molding in which shaping and cooling are simultaneously performed by blowing compressed air from a single compressed air supply source while discharging compressed air is performed to achieve energy saving for manufacturing hollow molded bodies. A blowing apparatus 10 of a stretch blow molding apparatus 11 includes a compressed air supply source 32 configured to send out compressed air adjusted to have an air pressure at which an object to be shaped e is inflated to be shaped into a hollow molded body, an inflow passage 33 through which the compressed air from the compressed air supply source 32 flows to the internal space of the object to be shaped e disposed in a blow mold 8, and a non-closed outflow passage 34 through which the compressed air flows out from the internal space of the object to be shaped e to a discharging space outside the blow mold.

Abstract: Fixation of a container shape of a hollow molded body is not completed during a blow molding process but is completed during an ejection process of an ejection section, thereby shortening an operation time in a stretch blow molding section, and improving the production efficiency of hollow molded bodies by shortening the time required for the blow molding process during a molding cycle. Cooling air is blown into the inside of the hollow molded body disposed in the ejection section in the ejection process C during the blow molding process B in the next molding cycle to cool the hollow molded body disposed in the ejection section to solidify the container shape.

Abstract: A preform of injection-molded PET has a body wall thickness of 3.0-4.5 mm. The preform is high-temperature mold-released from an injection cavity mold and an injection core. Pre-blowing of the preform is restricted at 5±0.5 seconds after the mold release, at a temperature of 112-117° C. of the pre-blow mold, and for a pre-blowing time of 0.5-1.0 second. Air blowing is applied to expand only the body of the preform. Stretch blow molding is performed restrictively at 3-4 seconds after the mold release from the pre-blow mold, at a temperature of 103-107° C. of the blow mold, and for an air blowing time of 6-9 seconds, thereby stretch blow molding the preform into a bottle and simultaneously heat setting to impart heat resistance to the bottle.
